Under normal circumstances, many people are not very clear on how to distinguish whether the headlights are flooded or fogged. They often think that it is water when they see water droplets. In fact, there is a way to determine whether the headlights are flooded or fogged, and that is to check the traces of water flow.
We know that if water enters the headlight, it usually enters from above the headlight and then flows under the headlight, which will form obvious water flow traces, similar to a waterfall. Even if the water is dry, there will be some traces left, just Like a snail's path, there are traces that experienced maintenance personnel can see.
How to deal with it?
If you see that the headlights only form water vapor below and the tops are still very clean, then it is generally a normal situation of fogging. It is recommended to put some desiccant in it and turn on the headlights often, and dry the inside by turning on the lights. The water vapor usually dissipates in about a week.
For the cleaning work in the engine compartment, it should be wiped with cotton silk or cloth, or blown with high-pressure air, so as to avoid "wetting" in the engine part as much as possible.
If the water accumulation inside the headlight is serious, then disassemble it, open the lampshade, and after drying, check the surface of the headlight for damage or possible leakage. If no abnormality is found, Chungu recommends replacement. Headlight rear cover seal and breather.
In winter and rainy seasons, it is best to develop the habit of checking the lights on a regular basis, especially after the vehicle is wading. Early detection and early remediation, and timely elimination of faults in the budding stage, are the best choices for car maintenance.
